This is Theory's signature Etiennette blazer, reimagined as a knit with a shawl collar. Color is a bright white. Made of a rayon/nylon knit that feels like a ponte with more structure. Unlined. In excellent condition. Clean, no marks or wear, white is impeccable. Size M. See photos for measurements. I find this suits about a size 6-8 in Theory, I wear a size 8 in the wool Etiennette for a comfortable fit that allows for layering, and I took a Medium in this jacket as well.
